TOY ELECTRIC LOCOMOTIVE Filed April 9, 1932 Patented Jan. 15, 1935 UNITED STATES PATENT OFFEQE TOY ELECTRIC LOCOMOTIVE to said R-osenthal Application April 9, 1932, Serial No. 604,274

2 Claims.

This invention relates to toy electric locomotives, and more particularly to the idea of employing the locomotive propelling or driving mechanism for purposes or in directions other than that of propelling the locomotive.

It is, therefore, a broad object of this invention to provide a locomotive in which the propelling or driving mechanism is arranged or adapted to be connected or is actually connected to mechanism other than that associated with the propulsion of the locomotive.

For example, there may be attached to the rotor shaft of the motor a transmission element such as a pulley or gear to be belted up or geared to said other mechanism or the driving wheels may be arranged to be placed in frictional engagement or otherwise with a member to be driven thereby.

It is also an object of this invention to provide a toy electric locomotive in which the rotor unotor) is adapted to be operatively disengaged from the driving gear for the purpose of applying the full power efficiency of the motor to transmission mechanism other than the driving gear.

In one instance, the pinion may be operatively disengaged from the rotor shaft, or the pinion may be shifted out of "operative engagement with the other driving gear.

For specific embodiments of the inventions herein described, reference is made to the accompanying drawing, wherein:

Fig. l is a plan view of the bottom of a toy electric locomotive which shows the drive pin- 35 ion connected to the armature rotor by a clutch arrangement.

Fig. 2 is a detail view of the construction shown in Fig. 1.

Fig. 3 is a detail view of an alternative clutch construction.

Fig. 4 is a section on line -10 of Fig. 3.

In the accompanying drawing like numerals indicate like parts.

Referring specifically to Figs. 1 and 2, 1 indicates the locomotive body in which is mounted the propelling mechanism comprising the motor 2, driving gear 3, 3, and driving wheels 4, 4. The motor comprises the pole pieces 5, 5, rotor 6, rotor shaft 7, and commutator 8. On the rotor shaft is mounted a pinion 24 which is normally in mesh with gears 10, 10, of the driving gears 3, 3. The sleeve 22 carries a binding screw 22' which enables the sleeve to be detachably secured to the shaft 7. With the sleeve in position as shown in Fig. 2, the binding screw 22 holds the sleeve and the sleeve retains the pinion 21 out of engagement with the gears 10. The pulley 11 can be taken off by loosening the screw 22' and then the spring 23 will cause the pinion to reengage the gear 10.

Pinion 24 is held in constant mesh with gears 10, 10, but is provided with a plurality of ra dially arranged internal notches 25, 25, communicating with a central bore 26 therein. The pinion is mounted on a collar 27 mounted on the rotor shaft and provided with radially extending teeth 28, 28 corresponding to the notches 25 in the pinion. Instead of the pinion being shifted out of mesh it is the collar element 27 which is thrown out of mesh with the pinion 24, the said collar constituting a sort of clutch for bringing the pinion and other driving gear into operative engagement with the rotor. As will be observed, the said collar 27 has a pair of diametrically opposed notches 29, 29 at the end opposite the toothed part which are arranged to register with a transverse hole 30 in the shaft 7. A pin 31 is inserted through the notches 29, 29, and the hole 30, said pin acting as guide along which the collar 27 is adapted to slide. Said pin also keeps said collar in constant operative engagement with the shaft. Normally the collar 27 will be projected by the spring 23 so that the teeth 28, 28 will be engaged in the notches 25, 25 of the pinion. In the event it is desired to disengage the rotor from the pinion, the collar is pushed inwardly against the action of the springs. In this construction the pulley 36 has a sleeve as before and carries a binding screw 22' to hold the pulley in position to keep the collar 27 disengaged from the pinion 24. When the screw 22 is loosened and the pulley removed, the spring 23 pushes the collar 27 back and makes the teeth 28 thereon engage the notches 25 of the pinion.

In the arrangement disclosed in Figs. 3 and 4 neither pinion nor rotor are shifted. The pinion 32 is held in constant mesh with gears 10, 10 but is of itself loosely mounted on the rotor shaft. The pinion 32 is provided with one or more longitudinal slots 33 therein. The shaft has a keyway 34 arranged to be alined with the slot 33 of the pinion and both are arranged to receive a common key 35 adapted to be shifted into and out of engagement with the slotted sleeve to operatively connect and disconnect the pinion from the shaft. Preferably this key is made integral with the sleeve of the transmission element, such as pulley 36. When said sleeve is slid in fully it operatively connects the pinion to the shaft, but when the sleeve is pulled. out so as to retract the key from the slotted sleeve then it operatively disconnects the pinion, but preferably said transmission element in its in or out position is always in operative connection with the shaft. The pulley 36 has a sleeve which again carries a binding screw 22f which can be tightened to hold the pulley' in such position that the pinion 32 will be connected to or disconnected from the rotor 6.

It will be obvious that many changes and modfined in the following claims.

Having described the invention, what I is claimed is:

1. In a toy electric locomotive including a rotor shaft and having drivewh'eels, gearing in-- eluding a pinion transmitting motion from the shaft to the drive wheels, clutch means slidable on the shaft for connecting and disconnecting the pinion therefrom, and a pulley having a sleeve to actuate the clutch means to disconnect the pinion from the shaft when the pulley is mounted on the shaft to be driven thereby.

2. A toy electric locomotive including a rotor shaft and having drive wheels, gearing for connecting the rotor to the drive wheels, said gearing including a pinion, clutch means for connecting the pinion to the shaft and disconnecting it therefrom, said clutch means being carifications may be made in the invention without g nied by the shaft and being encircled by the pindeparting from the true spirit and scope as de'-' ion when the pinion is connected to the shaft and a pulley having a sleeve to actuate the clutchm'eans and disconnect the pinion when the sleeve and pulley are mounted on said shaft to be driven thereby.
